Note 1: The reference group for recall score and willingness to use a mask was the no-stimuli control condition. The reference group for sentiment score was UK government’s text guidance, thus the number of observations was smaller than that of the other outcome measures. The reference age group was 18–39 years old, the reference ethnicity group is White, and the reference education group is with degree
Note 2: Adjusting for covariates did not affect the sign and significance level compared to non-adjusted analysis (not shown)
